. Thom-Pelle objec of: t is n nt n s toqgvrovideafastener for refrigerator. doors i ii' l ke, ha ll'overcome t above obj (actionable fea by positively shutting, andholding the door inlclesed position, and yet prmitlthe sameto easily opened at w I Anotherobjectisfthe provision of a door fastener of extremely simple construction and having substantially but three working parts, namely, a bolt, spring and roller.

Another object is to provide the latch member .of my invention with a novel arrangement of latch bolt and spring, which bolt when in engagement, is adapted" to keep constant tension against the door, thus 7 insuring a sealed closure of the same even when the door in due time shrinks away from the j amb, as the bolt when in wedging engagement. never reaches its final at-rest position.

A further object made possible'by my g the door tightly shut as shown 1n Flg. 1.

novel fastener arrangement, is to provide the bolt with a' common padlock forlock ing the door when desired.

Other objects and advantages of this invention will appear with reference to the subjoined specification and the accompanying sheet of drawings, in which v Figure 1 is a top view, showing a portion of a refrigerator door and its jamb with my invention applied thereto and shown in closed and locked position. The jamb and part of the latch member of my device is shown in section.

Fig. 2 isv a top viewanalogous to Fig. 1

closed position.

F g-si w ing the latch member of the fastener in place thereon with the latch bolt in the housing.

Referring to the drawings and; the figures thereof: The number 10 indicates a door,

such as. a refrigerator door and ishinged .lge view of the door show a I I in, the ordinary manner to thedoor frame (not-shown). Opposite the hinge side of thedoor is secured the latch member 11 o y nv nt sists of a housing '12, preferably semhcylin; dri'cal in shape'with Outwatrdlyextending flanges 13, for its securement to the door: s, by bolts 14:.

Thehousing isprovided at its inner end witha roundfhole 15., and at its outer end with a squarehole 16 in alignment with the former hole, 1( ,iS a, bolt adapted to 'iit and operate within the said holes; the head 18 the i qua ed to er espo it the square'hole 16, andits inner'end forms a shoulder against which a coil spring 19 abuts. "Said coil spring encircles the shank 20 of the bolt and is supported thereon and. within the housing, and abuts against the inner face of the latter as at 21.

One end'of. the bolt is threaded and is provided with a nut and jam nut 22 which limits the outward travel of said bolt to its at-rest position as shown in full lines Fig. 2, andalso provides anadjustment for the spring 19 which latter is of; grea strength.

The bolt when in engagement wedges The latter member con- The engaging member of my invention is denoted in general by the number'23, and

consists of a roller disc 24 supported within a bracket 25 on a shaft 26. The bracket is secured to the face of the jamb 27 by bolts 28.

In Fig. 1 the spherical head of the bolt is shown in contact with the disc 2st and considerably back of it when viewed from the front. The outward pressure exerted by the coil spring 19 on the bolt 17, wedges the head of the latter tightly against the its diametrical center to a position behind.

the disc, which is the shut position of the door and the locking position of my fastener.

To open the door, the operator pulls the handle 29 thereon, and my device goes through the reversal operation to that above.

When the bolt passes the diametrical center line of the disc, it is freed and again assumes the normal position as shown in Fig. 2.

In some cases a padlock or other lock may be desirable on the fastener to secure the door at night or at other times. To accomplish this, I provide the head 18 of the latch bolt 17 with a suitable hole 31 between the housing 12 and the engaging member 28 iorthe slipping therethrough the bow 32 of a padlock 33; As shown in Fig. 1, the padlock confines the said latch bolt of my invention in such a position that it cannot be withdrawn from engagement with the disc roller 24.

' gether with the device which I now consider to be the best embodiment thereof, I desire to have itunderstood that the device. shown is merely illustrative and that such changes maybe made when desired, as fall within the scope of the appended claim.

-What I claim as new and desire to secure by Letters Patent 01" the United States, is

In a latch device, a housing, means scour ing said housing to a door a doubleacting latch bolt slidably mounted in said housing, a coil spring urging said bolt outward from said housing, means governing the protru sion of said bolt, a keeper member adapted to be secured to the outer face offthe door jamb provided with a roller adapted to engage said bolt, means for rigidly locking said bolt in extendedposition by a padlock on the bolt between the housing and the keeper member and said bolt being so 'ad-- justed that when the door is fully closed it still exerts a pressure against said roller tending to close the door further.

In testimony whereof I afiix my signature.
